DUST-COLLECTOR.

Specification of Letters Patent.

Patented June 5, 1217.

Application filed J'anuaryl3, 1917. Serial No. 142,122.

To all whom it may concern:

Be it known that I, JEssra lines, a citizen of the United States ofAmerica, and resident of Bellevue, in the county of Campbell and Stateof Kentucky, have invented a new and useful Improvement in Dust-Collectors, specification.

An object of my invention is to produce a dust collector for hot airfurnace pipes, which is capable of being cleaned repeatedly withoutimpairing the effectiveness thereof and which may be placed in positionand used within the pipes without diminishing the supply of air passingtherethrough.

This and other objects are attained in the construction described in thefollowing specificationand illustrated in the accom panying drawings, inwhich:

Figure l is a plan view of a dust collector embodying my invention, inposition in a hot air furnace pipe.

Fig. 2 is a sectional view of the furnace pipe with my improved dustcollector mounted therein, taken on the line 22 of Fig. 1.

Fig. 3 is a sectional view of the furnace pipe and my improved dustcollector, taken on the line 3-3 of Fig. 1.

Fig. 4 is a plan view of a modified form of dust collector embodying myinvention, mounted in a furnace pipe.

Fig. 5 is a sectional view of the construction disclosed in Fig. 4 andtaken on the line 5-5 thereof.

My improved dust collector consists of a frame 6 of sheet metal, havinga series of vanes 7 located therein and secured in the sides thereof byhaving their ends passing through slots 8 in the frame and provided withlugs 9 adapted'to be bent into engagement with the sides of the frame,the slots being inclined to hold the vanes in the inclined positionsshown. At each end of the frame. hooks 10 and 11 are provided, thesehooks being adapted to engage the top edges of the ends of the sheetmetal housing 12 provided for the register 13 located in the floor 14,the housing communicating with the usual hot air pipe 15. The innersurfaces of the frame andboth surfaces of each of the vanes are coatedwith fire proof cement which, while still inits adhesive condition.permits of the attachment thereto of a coating of flufiy asbestos 21.The coatof which the following is a ing of asbestos is suficientsubstantially to close the spaces between the frame and vanes andbetween adjacent vanes, to prevent the passage of air therethroughwithout having to be brought into contact with the asbestos. Cardedasbestos is employed for this purpose so as to alford a sufficientlyporous mass to allow the air to pass through it freely and yet having asufficient number of minute flakes to prevent the passage of dustthrough the collector.

The construction disclosed in Figs. a and 5 is adapted to be used inround pipes or o be located in the pipes immediately below the housing12 in which the register is located, as disclosed.- This modified .formconsists of a circular frame 16 of sheet metal having its upper edgeturned over to form a series of supporting lugs 17 adapted to rest onthe bottom 18 of the housing 12 in which the register 13 is located,these lugs supporting the collector Within the pipe. Extending acrossthe frame 16 and secured therein in the same manner that vanes 7 aresecured in frame 6 of the construction disclosed in Figs. 1 to 3inclusive, are a series of vanes 19, which are located in vertical,horizontal, and inclined positions. By thus staggering and positioningthe vanes, the air passing through the pipe is baflled and addition tocementmg the asbestos to the vanes 19, I also coat the interior of theframe 16 therewith to aid in the collection of dust passing through theipe.

My improved dust collector is placed within the pipes in the positionshown, and used until the dust collected thereby has impregnated thefibers of the asbestos to such an extent as to completely fill theinterstices thereof. Then the collector is lifted from its positionwithin the pipe and is carried to an open flame. The flame is thenallowed to pass through the asbestos and to consume all ofthe dustcollected thereby. This completely cleanses the collector, the ashes,should any remain, being easily removed by shaking the frame slightly.My improved construction is one particularly adapted to be sterilized bythe passage therethrough of a flame, in that the heat necessary tocleanse the collector will not detrimentally affect its construction byweakening or warping it. In other constructions heretofore employed, theuse of heat as a cleansing agent is not possible since they are toodelicate for such a treatment and can only stand the action of agenciesas air and Water. In the use of water in connection with dust collectorshaving such delicate constructions and employing thread-like collectingmaterial therein, the tendency terial and to render it inefiective forthe was provided.

purpose for which it invention, what Having thus described my I claimis:

1. A dust collector consisting of a sheet metal frame, a series ofparallel metal vanes located therein and spaced therefrom and from eachother, and a coating of dust oceluding fire proof material attached toboth sides of the vanes and tothe inside of the frame, said vanes beinginclined at angles such cleansing I of the water is to mat the mato thedirection of the normal passage of air through the collector.

2. A dust collector comprising a sheet metal frame adapted to be locatedwithin an air pipe, a series of sheet metal vanes .located thereinspaced therefrom and from each other and adapted to bafie the airpassing through the pipe, and carded asbestos attached to the vanes andto the interior of the frame and extending into the spaces between thevanes and the frame, said vanes being inclined at angles to thedirection of the normal passage of air through the collector.

In testimony whereof, I have hereunto subscribed my name this 11th dayof January, 1917.
